The holy text of the Nirankari Mission, the Avtar Bani Book, Sant Nirankari Mission summarizes the core ideas of the Sant Nirankari Mission. It may actually be seen as the Mission's version.

A spiritual organization, the Sant Nirankari Mission (SNM) is also called the Universal Brotherhood Mission. The Sant Nirankari Mission is an allen compassing spiritual movement committed to the welfare of humanity rather than a brand-new religion or a sect inside an established one.
